Interesting effect! It looks almost like Infrared. Composition overall is pretty good. But I don't know if the effect you chose for this image was more beneficial than a regular photo. There is a lot of detail that is brought out by the effect, particularly in the trees in the upper right corner. I think it draws the eye away from the central subject here.
Focus is pretty good but I really can't comment on much else here.
love the composition, but don't like the execution. Realize you did it to make it stand out. It's different as it is and would have been beautiful in color. It's a really good photograph and your technicals are good. Really like the cropping, but personally do not like your finish, whether sepia or whatever. For me it went from an a to a 4.
